-Removed-If that date refers to the first day of creation, I do not
think that date comes very close to the true date. But I
can not say that I know when it was. I have no idea if
anyone at all celebrate this date. I think the Jews believe
one of there Holy days on their calendar, which is the start
of the Jewish civil year I understand, marks the first day
of creation. But that day would fall on different days each
year on the calendar we use. That is about all I have to
offer; but I just thought of something you might want to
check, that is Wikipedia. Maybe there is something there
that would lead you to an answer to your question.
Originally posted by FMFCertainly not a complete answer, but at least it tells you that commemoration of this date isn't so widespread that everybody has heard about it.
No matter how one looks at it, "Why should anyone celebrate this date?" is not an answer to the question "How widespread is the celebration or commemoration of this date?"
